Teori Pemanasan Corona Matahari berdasarkan tafsiran Alquran dan Sains

mbhcsf

Majoriti pulak tak setuju yang haba boleh bergerak sendiri dalam vakum pasal mana ada zarah kan? tapi ada ahli panel kata vakum leh menyimpan haba atau pada pendapat saya mungkin boleh menyimpan energy pada suhu tertentu saja? wallahualam.

sapa diaaa? depa tak setuju pulak dahh..tulah depa nilah..awat tak setuju tu?
sayang you ni ..ish ish ...semua setuju lah haba boleh bergerak sendiri dalam vakum, tapi menerusi RADIASI EM wave yg Papa cakap tu rasanya. Cuba baca pelan pelan. Take your time. It's ok.
bila haba tu bergerak secara radiasi , sayang....maka tak perlu zarah ler dear.


okay , haba atau energy transfer ( ni Encik Saden preferred istilah ahem ahem) ni boleh berlaku dalam 3 cara: konduksi, perolakan, radiasi tapi yg conduction and convection ( perolakan ) tu kena ada medium pemindahan tenaga - iaitu zarah zarah ler dear. Tapi radiasi well tak perlu medium.

Corona tu ialah matahari punya plasma atmosphere, sebhgn daripada matahari . Dia duduk atas matahari.  tapi mmglah suhu dia tingi sebab dia ni simpan tenaga dari mana tenaga tu ..haa nilah yg para saintis dok pikiaq ( tak kisah lah saintis eskimo, ker antartika ker Japan or what not yer ). Tapi depa usulakan teori yg
menurut depa boleh terangkan tai tak sepenuhnya. NI bukan KELEMAHAN tau nak cakap depa tak tahu ini adalah sifat keterbukaan dan merendah diri.
tapi kebanyakannya kalau u rujuk Papa punya pos yg english tu ... centred around magnetism.....


you ada sebut heat law..i think you mean apa yer ?


tapi pada saya suhu kat plasma korona tu tinggi sebab plasma korona tu tak mencapai keseimbanagn terma maksudnya dia dok kumpul energy tapi tak boleh nak cool it off sebab tu dia tinggi dan sebab apa dia sentiasa inggi dan bagaimana dia maintain suhu tinggi ..ni i tak tau sama juga i tak tahu macam mana staeady rate? state energy transfer  kepada plasma..tapi saya juga seearch the reading dari nasa website and etec and i mmg tak faham astronomy ni ..sangat  dear oii... andaikan  is juga berkaitan dgn magnet juga like  
ni i merapu jer tau :

adakah berkemungkinan besar yg magnetic field matahari yg buatkan charged particle tu dok tak boleh cool it of like somehow magnet tu yg affect the motion of zarah zarah ion tu / partikel tu?

anyone?



berapakah suhu UNIVERSE?

jom discuss apalagi yg poerlu kita clarify?

sebab i pun taktahu jugak....

yg kat bumi adalah 3 -pepajal, cecair dan gas and kat space  ada satu plasma i pun tatau rupamacammana actually tapi persoaln ni mmg interesting

Plasma = ions = charged particles...tapi tak sama dgn plasma darah

kinetic behavior sama dgn gas, cuma tambah sikit iaitu dia jugak boleh dipengaruhi oleh daya elektromagnetik (pasal dah ada charge)

mbhcsf

of course not ...plasma darah compose  of proteins, glucose etc etc .....


kinetic behavior sama dgn gas, cuma tambah sikit iaitu dia jugak boleh dipengaruhi oleh daya elektromagnetik (pasal dah ada charge)

oh i see....yep that explains it then....

haiyaaa.... hati mau cakap lain, tapi type lain lar, sorry my dear

betul lar tu, bergerak melalui radiasi dalam ruang vakum namun oleh sebab vakum tu takde zarah maka tiada penyerapan haba dalam vakum, yg ni betul kan

The Temperature of the Universe (2.7281K)

ada satu soalan utk you berkaitan ngan vakum ni ;

My understanding of space is that it is a vacuum, i.e., devoid of pretty much all matter, just empty space. Also from my amazingly limited knowledge of physics I understand that in order for a force to create movement it must act upon something. So if a spacecraft fires its rockets into space, a vacuum, what is this force is acting upon? If there is nothing there, what are the rockets pushing against to cause the ship to move?

camna yer

I just attend mu lecture just now, vacuum is defined as a region of space where the pressure read as negative gauge. Which means that vacuum allows particle to exists too...

mbhcsf

an this would imply....that a word such as vacuum can be defined in many ways....yes

eh Ensem you mentioned a term there " pressure read as negative gauge" well ...it implies that certain kind of force / area  is of important concept...well for one space has no air so ..? the force' elements being well let say quite negligible but i dunno much on teh volume though.....


so suhu space ialah 2.7 ?/ Kelvin - rendah jer kan?

my answer would be :

the force of that rocker firing is needed to act on ANOTHER FORCE ...

i could think of the earth gravitational field lah kot. sebab ini juga bergantung kat mana spacecraft tu berada  kar orbit ker or post orbital  dan kelajuan yg spacecraft tu perlu ada untuk melepasi sesuatu  level  orbit tu lah kot

yea, apparently vacuum has a lot of meaning. we really need to define vacuum in every text that we encounter.

just like the mathematical symbols that a writer use in his/her paper.

apa kaitan pressure, vakum dan partikel?
apa maksud positif, zero dan negative gauge ?

newton law ke 3 (for every action there is an equal and opposite reaction), yg already kat outerspace.

actually, terfikir akan satu experiment dimana sebuah model roket dilancarkan dlm ruang vakum artificial. Nak tau kemana perginya haba dari pembakaran gas roket tu? Adakah ia sepenuhnya ditukar kepada tenaga kinetik atau radiasi atau camna yer?

tu yang terjumpa soalan tu and share kat sini.

Yup, rocket propulsion lebih efficient di angkasa lepas berbanding di bumi. See.. kadang-kadang suatu keadaan tu mudah tapi mengelirukan kepada orang yang tak nak berfikir. Misalnya, bumi bulat tapi selama beribu tahun manusia kata bumi flat. Samalah dengan enjin roket ni. Sebab tu la saintis yang menemui hukum-hukum fizik ni (macam newton/einstein) sangat dihargai. Mereka faham apa yang orang lain tak faham...

soalan Putra tentang

roket launching by a spacecraft in the outer space tu is basically  you not nak acts against apa daya?

kalau launching dari bumi ker orbit -  roket tu dilancar sebab nak overcome the earth's gravitaional pull tapi onced in the orbit spacecraft tu ? launching the roket untuk just for maneuvering purposes or to  overcome the earth's gravitational pull ker  lagi ?

sebab apa yg berlaku ialah spacecrat tu akan berada pada level tertentu kat orbit , kan? mesti ada kelajuan tertentu samaada nak stays put or kalau nak goes further kena increase the velocity to overcome another daya ?? lah kan? adakah daya itu still  daripada erth's gravitaional field?
i pun curious jugak ni .

Newton kata "for every action there is an equal and opposite reaction". Lupakan tentang graviti dan lain-lain dulu. Satu kapal angkasa berhenti/terapung di tengah-tengah angkasa lepas yang tak ada graviti. Hanya kapal angkasa dan enjin roket dia. Katakan kapal tu ada 2 enjin roket setiap satu di sebelah kiri dan kanan badannya. Tiba-tiba kapten kapal pasang enjin di sebelah kiri, apa akan berlaku? Kapal akan ke kananlah. Sebab apa? Sebab tujahan enjin roket merupakan satu daya yang mempunyai velocity tertentu. Velocity tujahan enjin roket akan menjadi velocity kapal angkasa tu jugak. Sebab "for every action there is an equal and opposite reaction".

oh i see...allright . i got it ..so hmm....this particular third law of motion does applicable in outer space... o ok.

Sorry, later I realised that definition ni x sesuai dlm konteks perbincangan ni.

Gauge Pressure kene set 0 kt tekanan atmosfera d mne kite berade skrg. Hence klu ade 1 container d mne tekanan die lg rendah, negative Gauge akan dibaca, so ia ditakrifkan sebagai vakum.

Since lecturer Chem Eng yg bg definition ni, aku rse ia digunakan dlm industri je. Psl Gauge Pressure tu sendiri relatif, so kite xleh r bwk die ke matahari.

Silap soalan kot...

Ko ckp 'ke mne perginye haba pembakaran", so haba tu sume pegi radiasi kot, xde yg tuka gi tenaga kinetik. Pergerakan roket x bergantung kpd haba pembakaran, just momentum fuel yg dipancutkan..

Rsenye ko nk tnye "tenaga dlm fuel tu ke mne", tol ke?

Tenaga tu tu mainly digunakan utk naikkan energy particle2 product pembakaran. Since tenaga kinetik particle ni naik, temp pun naik gak. Kt situ kite dpt haba. Temp fuel to measures tenaga kinetik yg diorg ade, indirectly measures waper laju roket leh gerak.

Selain itu, tenaga dr fuel leh gak memanaskan vessel d mna reaction tu jd. Situ inefficiency die. Ade gak tuka pegi getaran (kt Bumi kite recognise sebagai bunyi).

Velocity tujahan enjin roket akan menjadi velocity kapal angkasa tu jugak.

Momentum kot... Even if velocity fuel laju, tp klu mass die kecik, die menyumbang sebhgn kecil dr motion tu je.
